Compressible Kelvin-Helmholz Instability

Compressible convection in a simultaneous Dedalus/Athena simulation

2D compressible convection simulation, in which the top half of the box is simulated using the Athena code, and the bottom half of the box is simulated using Dedalus.
The smooth features in the image demonstrate the two codes, using very different numerical techniques, can be stitched together to run a single simulation.
